Can you please solve this for me? Thank you

Consider the hypothetical reaction A+B+2C2D+3E where the rate law is Rate=t[A]=k[A][B]2 An experiment is carried out where [A]0=1.0102M,[B]0=7.0M, and [C]0=2.0M. The reaction is started, and after 7.0 seconds, the concentration of A is 3.8103M. a. Calculate the value of k for this reaction. k=L2mol2s1 b. Calculate the half-life for this experiment. Half-life = c. Calculate the concentration of A after 13.0 seconds. Concentration=M d. Calculate the concentration of C after 13 seconds. Concentration=M
